DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mechanical parking device for moving a vehicle in a lateral direction, and more particularly to a structure of a traversing mechanism of the vehicle.

[0002]

2. Description of the Related Art Generally, mechanical parking devices of this type include:
There are various types such as elevator type and plane reciprocating type, and the pallet for mounting the vehicle is moved laterally by the traversing mechanism between the elevator and the parking space, or between the traveling trolley and the parking space. I have to. In this traversing mechanism, as disclosed in Japanese Patent Application Laid-Open No. 4-80475, a turning arm is rotatably mounted on a lifting platform, and an engaging roller is provided at the tip of the turning arm. There is a guide formed on the bottom surface of the pallet. Then, the turning arm is rotated forward or backward,
The engaging roller is engaged with the guide portion to transfer the pallet from the parking space to the elevator, and conversely, the pallet is transferred from the elevator to the parking space.

[0003]

However, in the above-mentioned mechanical parking device, there is a problem that the traversing mechanism only moves one pallet in the horizontal direction, and the transfer efficiency is poor. That is, when a pallet is present on the elevator, after moving the pallet of the elevator, another pallet from the parking space must be moved to the elevator, and two pallets of the elevator and the parking space are required. When the pallets are moved, they cannot be moved at the same time. Therefore, a mechanism using a belt or a chain as the traversing mechanism can be considered. In this traversing mechanism, the parking space and the pallet of the elevator can be traversed simultaneously. However, in this traversing mechanism, since it is necessary to reduce the moving speed at the initial stage and at the time of stopping the pallet to perform smooth traversing, it is necessary to mount a deceleration mechanism and an acceleration mechanism, and the structure and control become complicated. Will occur. In particular, since the two pallets are simultaneously moved in the horizontal direction, it is necessary to synchronize the deceleration, the constant velocity, and the acceleration of the two pallets, which causes a problem that the structure and control become extremely complicated.

[0004] The present invention has been made in view of the above point, and is intended to simultaneously and laterally move two pallets so that pallets can be smoothly and efficiently transferred.

[0005]

In order to achieve the above-mentioned object, the present invention provides means for rotating two pin-connected swing arms and engaging both swing arms with a pallet. One pallet is to be traversed at the same time. Specifically, the means taken by the invention according to claim 1 is that, first, while a plurality of parking sections on which pallets are installed are formed in parallel in the lateral direction, the pallets are moved in the lateral direction between the parking sections. It is assumed that a mechanical parking device is provided which is provided with a traversing mechanism for moving the vehicle along with the pallet by mounting the vehicle on the pallet. On both sides of the driving-side parking section provided with the traversing mechanism, a passive-side parking section through which a pallet is carried in and out by the traversing mechanism is formed. Further, the traversing mechanism includes a first swing arm having a base end rotatably supported by the driving side parking portion, and a second swing arm having a base end rotatably supported by a distal end of the first swing arm. An arm, a pallet engaging member provided at a distal end of each of the turning arms and located at the driving side parking section and the passive side parking section, a driving unit for rotating the first turning arm, Revolving means for preventing rotation of the second swing arm so that the second swing arm performs only revolution with rotation of the first swing arm. In addition, an engaged portion is formed on the bottom surface of the pallet so that the engaging member of the traversing mechanism is engaged at a predetermined turning position of the two turning arms and is disengaged when the two turning arms rotate half a turn. Configuration.

[0006]

According to the first aspect of the present invention,
The pallet is moved laterally between the driving side parking unit and the passive side parking unit. For example, a traveling vehicle provided in the traveling space and a parking unit of a parking space formed on both sides of the traveling space The pallet is moving between and. In this case, when the driving means of the traversing mechanism is driven, the first turning arm rotates and the second turning arm rotates only by revolving without rotating by the revolving means.
Then, for example, when the two turning arms are rotated forward, the engaging member of the first turning arm is engaged with the pallet of the driving side parking portion at the turning position in the lateral direction, and the engaging member of the second turning arm is turned on. The two pallets are engaged with the pallet of the passive side parking unit, and the two pallets are moved to the adjacent side of the passive side parking unit and the driving side parking unit respectively by the half rotation of the both swing arms, and each engaging member is moved from the pallet. You will be leaving. When the two swing arms are reversed, the engagement member of the first swing arm is engaged with the pallet of the passive parking unit, and the engagement member of the second swing arm is engaged with the pallet of the driving side parking unit. The two pallets are respectively moved to the adjacent passive-side parking portion and the driving-side parking portion on the other side by the half rotation of the two swing arms. This allows the two pallets to move simultaneously and smoothly in the lateral direction.

[0007]

Therefore, according to the first aspect of the present invention,
The first swivel arm and the second swivel arm that are engaged with two adjacent pallets are connected to each other, and the second swivel arm revolves with the rotation of the first swivel arm. Since the two vehicles can be moved laterally at the same time, there is no need to perform two operations as in the related art, and efficient pallet transfer can be performed. In addition, since the pallets are moved in the lateral direction by rotating the two swing arms, the moving speed of the pallets changes according to a sine curve (Sin curve), and the pallets are decelerated at the initial stage and at the time of stopping. Can be moved smoothly. In addition, since there is no need to provide any speed reduction mechanism or the like, the two pallets can be moved smoothly with a simple mechanism and simple control. Further, since the traversing mechanism can be hidden by the pallet, the traversing mechanism can be made invisible.
